Aerospace aftermarket outlook strengthens as RBC sees 2027 growth accelerating

RBC Capital Markets raised its forecast for commercial aerospace MRO activity growth in 2027 to 11.6% from 9.6%, citing a survey that challenges growing investor caution. More than 30 maintenance providers reported third-quarter MRO sales growth of 11%, parts purchasing growth of 13.4%, and engine MRO growth of 12.4%.

Analysis

The investable signal is a possible mix shift toward recurring aftermarket revenue, which can cushion aerospace earnings when new-aircraft deliveries are volatile. The clearest potential beneficiaries are providers with engine-repair capability, approved repair processes and available shop capacity—not every company labeled “aerospace.” AAR, GE Aerospace, Safran and Rolls-Royce merit review for disclosed aftermarket exposure; verify segment growth, capacity and pricing rather than extrapolating the survey to consolidated results. Airlines may face the opposite effect through higher maintenance expense, partly offset by improved fleet availability.

The main caveat is that parts purchasing can lead actual shop visits—or reflect inventory replenishment—so it is not yet proof of durable end demand. A small provider survey also may not represent the full market. Near term, earnings calls and monthly operating updates should reveal whether utilization, engine visits and aftermarket orders confirm the signal. Over 6–18 months, labor, repair-slot and parts constraints could support pricing, but also cap throughput and defer revenue. A reversal in provider order trends, inventory normalization, or weaker engine-shop activity would falsify the thesis; broad airline fleet utilization and maintenance commentary are useful cross-checks.

Key Decisions for Investors

• Build a watchlist for a relative long in verified aftermarket-heavy businesses—such as AAR or GE Aerospace—against more delivery-cycle-sensitive aerospace exposure. Initiate only after company disclosures confirm aftermarket growth and capacity conversion; avoid assuming the survey maps directly to earnings.
• Use the next 1–3 months of earnings commentary to check engine shop visits, aftermarket order trends, pricing and capacity utilization. If purchasing remains strong but visits or reported aftermarket revenue do not follow, treat the signal as inventory timing and do not add exposure.
• Potential 6–18 month upside rests on constrained repair capacity supporting pricing; monitor labor availability, turnaround times and parts access. Capacity bottlenecks that prevent volume conversion would weaken the earnings case even if demand remains firm.
• No broad sector trade is warranted from survey data alone. Reassess if provider orders decelerate, airline maintenance commentary softens, or company guidance fails to validate aftermarket momentum.
